Allen-Bradley 1756-OW16I | ControlLogix Discrete Output Module

Product Overview

The 1756-OW16I from Allen-Bradley is a high-performance discrete output module for the ControlLogix platform. It provides sixteen individually isolated channels with Normally Open (N.O.) relay contacts. This module operates efficiently across 5–125V DC and 10–240V AC voltage ranges, making it highly versatile for industrial automation.

Each channel delivers output currents of 1 A at 5–30V DC, 0.5 A at 48V DC, 0.22 A at 125V DC, 1.5 A at 120V AC, and 0.75 A at 240V AC at 50/60 Hz. The module also has a pilot duty rating of C300/R150.
